OLIVE MESSICK GLENN, OF WASHINGTON, DISTRICT OF COLUMBIA.

SURGICAL INSTRUMENT.

' Application flled February 21, 1917. Serial no. 150,153.

To all may concern:

' 1 qBeit known that ll ULlvnMnssioir GLENN,

a citizen, of the United States; residing at Washington, in the District of Columbla,

have invented certain new and useful Improvements in Surgical Instruments, of

which the following isa specification, reference being had therein to the accompanyy nvention relates to surgical instruin drawingi I a I ments'arulhasfor its ob]ect the provision of means for readily attaching and detach ing a speculum to a pocket flashlight, to enable an examination to be made of the throat, ear, nose or eye. 1

Another object is to provide a combined tongue depressor and light reflector that can be readilyattached to and detached from a. pocket flashlight which a surgeon may.

use not only to depress a patients tongue, but to illuminate the throat forinspection. With these objects in new, the invention consists in the construction, arrangement and combination of parts hereinafter described and particularly pointedout 1n the tend tolimit myself to the details of con str'uction.

The invention is. illustrated in the accompanying drawings in wh1ch Figure 1. is a side view, partly in 560M011.

of a speculum attached for an examination of the mouth and throat.

Figs. 2 and 3 are perspective views of the reflectors of Fig. 1.

Fig. 4 is a similar view of a. modification which may be used in connection wlth the battery casing of Fig. l.

, Fig.5 is a perspective view of a collar'for attaching the reflectors of Fig. 1.

I Fig. 6 is a perspectiveview of an ear and nose speculum. r Fig. 7 is a similar viewof an eye speculum.

is a collar 4 having on its inner surface two Specification f Letters Patent.

Patented Dec. a, mi.

diagonally opposite longitudinal grooves 5 and 6 to receive the tonguesof the reflectors 7 and 8 respectively. The collar 4 and the reflectors 7 and 8 maybe securely clamped in position by a set screw 9.

erator may have an unobstructed view of the throat. The smaller reflector 8 serves to reflect the-rays of light which: strike it downwardly upon the larger reflector 7,

these rays being in turn reflected by the latter upon the roof of the mouth.

.In Fig. 4 I have shown a modification in which the tongue depressor and reflector 10 is made fiat, and with. an integral split ring 11 adapted to be slipped over the ring 3, and to be frictionally held thereon against turning.

Fig. o shows an ear and nose speculum 12, having an integral split ring 13 adapted to be slipped over the ring 3. The body of the speculum is preferably conicalwith the base, or larger opening at the end at which it is attached to the casing 1. Therays of light from the bulb 2 will be concentrated by the speculum and directed into the nose or car, the operator having an unobstructed View through the speculum.

In Fig. 7 the light reflecting surfaces 14. and 15 are secured together and so formed as to adapt the speculum to an examination of the eye. To the frame is attached a tongue 16 by which the speculum may be clamped to the casing 1, by means of the collar 4.

The several devices above described pro vide a ready and simple means for attaching and detaching the desired form of speculum to the battery casing. The latter is of such form as to be carried in the poclet, the speculum being detached if deslre What ll claim and desire to secure by Letters Patent of the United States is I 1. The combination with a self-contained pocket'electric lamp ,of a tubular form having a detachable lamp-socket adapted to he inserted into one end of the tube form by end of said tube form, of a spring collarsurrounding the bulb end of said tube form and having an outside diameter not less than that of said flange, a clamping collar arranged to be slid over said flange onto said spring collar and having diametrically opposite recesses in its inner face, areflecting tongue depressor and a reflector having holding tonguesor shanks arranged to be inserted into said recesses between the said collars, and a set screw carried by said clamping collar.

2. In a device of the class described, the combination of a source of light, a tongue essee? depressor having a reflecting surface, and

alight screen having a reflecting surface,

posed to the light radiating from said a source, and said reflec-tingscreen being so arranged in relationto the source of light and-the tongue depressoras to cause the upwardly directed light rays from the source to be reflected downwardly to the middle portion of the tongue depressor.

In testimony whereof I affix my signature.
